Driveshaft alignment

[arch_stanton]

I wrote about this same thing in another thread, I have owned this pete 378 since 2002 running as a dump truck and it has always had a little vibration that I could not find looked at drive line angles, carrier bearing,ect after another guy posted about his drive shaft off center line causing a vibration so I put a string line from center of trans u joint to center front drive u joint and I found 2 things. The carrier bearing was offset to the passenger side and the front driver was off set to the driver side caused by installing a torque rod wrong. I drilled 2 new holes in the carrier bearing mount and remounted the vibration is gone
